[CC 1976 §530.010; Ord. No. 619 §§1—2, 10-13-1953; Ord. No. 947 §1, 11-14-1967; Ord. No. 2179 §1, 11-10-1998]
A.
All sidewalks
constructed within a public or private street, avenue, drive, lane,
court, place and/or thoroughfare of like nature shall be Portland
cement concrete and shall be constructed as herein below specified.
1.
Width and thickness. Sidewalks herein proposed shall be
of One-Course Type construction, and shall be four (4) feet wide,
unless a greater width is deemed necessary by the City Building Commissioner,
and shall be a minimum thickness of four (4) inches except in driveways
where the minimum thickness shall be six (6) inches.
2.
Grade. The grade and alignment of all sidewalks herein
shall be set by a competent licensed Engineer and shall have the approval
of the City. All walks shall have a slope of one-quarter (¼)
inch per foot of width from the back of said walk toward the center
line of the street.
3.
Proportions for the concrete. The concrete mixture for
all sidewalks shall be proportioned by volume so that a cubic yard
of finished concrete contains not less than six (6) bags of cement
(94 lbs. each, net). The proportions of fine and course aggregate
shall be varied to produce the most dense concrete obtainable. The
volume of water used in gauging the mix shall not exceed six-and-one-half
(6½) gallons of water per bag of cement. The method employed
to measure the water shall be such as to take into full account the
amount of water contained in the fine and course aggregate.

of aggregate are damp loose volume.

4.
Water. All water used for mixing concrete shall be clean
fresh water from the mains of the St. Louis County Water Company.
5.
Mixing and placing the concrete. A pre-mixed concrete may
be purchased from a reliable company provided, however, such concrete
shall comply with these specifications. Where the concrete is mixed
on the site of the job it shall be thoroughly mixed in a rotary batch
mixer. The period of mixing shall not be less than two (2) minutes
after all ingredients have been placed in the mixer. Mixed concrete
shall be of uniform consistency and the mixing period shall be increased
if necessary to acquire thoroughly mixed concrete. Concrete shall
be transported to the forms in clean wheelbarrows and placed in the
forms by dumping, care being taken not to mix the concrete with the
subgrade.
6.
Finish. The concrete shall be carefully tamped in place
and finished without the addition of mortar. Joints shall be edged
and the walk finished by belting and floating. When necessary dry
mortar mixed in the same proportions as the mortar in the concrete
may be sprinkled on the surface to aid in finishing.
7.
Joints. The sidewalk shall be marked with dummy joints
at five (5) foot intervals and every tenth joint shall be made by
placing, between forms, at right angles to the forms, one-half (½)
inch premolded asphalt expansion joint, made to the cross-section
of the walk. Where the walk is placed against the curb a one-half
(½) inch premolded asphalt expansion joint, the depth of the
walk, shall be placed between the sidewalk and the curb. Where sidewalks
fill a space between a wall or building and a curb, a one-half (½)
inch premolded asphalt expansion joint shall be placed between the
sidewalk and the wall or building and the sidewalk and curb. In sidewalks
placed against concrete curbs the joints shall match those of the
curb, as nearly as practicable, except that the space between joints
in the sidewalk shall be not greater than six (6) feet or less than
four (4) feet. One-half (½) inch expansion joints shall be
placed on all sides of the square formed by intersecting sidewalks.
8.
Forms. All forms for this work shall be straight, free
from warp, and of sufficient strength, when staked, to resist the
pressure of the concrete with out springing. All forms shall be thoroughly
cleaned and greased before the concrete is placed against it. Forms
shall be neatly and tightly joined and securely staked to line and
grade and the expansion placed before any of the concrete is placed.
9.
Curing. As soon after final finishing operation is completed
and the concrete has set sufficiently to prevent marring, the top
surface of the sidewalk shall be entirely covered with thoroughly
wetted burlap. Burlap shall be handled in such manner that it will
not come in contact with earth or other deleterious substances. New
burlap and burlap that has been used for purposes other than curing
of concrete shall be washed before being used. The burlap shall be
kept thoroughly wet and remain in place for a period of not less than
three (3) days. At no time shall the top or side edges of the sidewalk
remain unprotected for more than one-half (½) hour. Forms shall
remain in place for twenty-four (24) hours and immediately upon their
removal the spaces on either side of the sidewalk shall be filled
with suitable material.
10.
Repair of sidewalks. Broken or damaged portions of sidewalks
shall be removed evenly at dummy or expansion joints. Forms shall
be placed evenly from remaining section to remaining section of walk,
overlapping the old sections with the forms. The same care shall be
exercised in placing the forms for replacing a portion of walk as
in placing forms for new sidewalks. Methods of finishing and curing
the concrete shall be as hereinbefore stated for new sidewalks.
11.
Work in freezing weather. Concrete laid in freezing weather
shall be protected so as to prevent damage to the concrete, the method
of protection used shall suit the degree of exposure.
12.
Protection of the work. Contractors and/or all others constructing
sidewalks shall take the proper precautions to protect all water,
sewer, gas pipes or other conduits and walls or other property from
damage. He/she shall take the necessary precautions to protect persons,
animals, and vehicles at all times. Should a suit for damages be instigated
this City assumes no responsibility.
13.
Cleaning. Upon the completion of this work all materials
not used shall be removed, and all litter shall be disposed of, and
the site of the work shall be cleaned to the entire satisfaction of
the City.
14.
This
Section does not apply to any part of sidewalks constructed from private
residences to the public walk.
[CC 1976 §530.020; Ord. No. 629 §1, 2-9-1954]
It shall be the duty of every owner of real estate to keep the
sidewalks, curb and gutter and driveway entrances adjacent to his/her
property and in the City, in good repair at all times and free from
irregularities and offsets in the surface thereof which may render
the same unsafe for use.
[CC 1976 §530.030; Ord. No. 629 §2, 2-9-1954]
Whenever the Board of Aldermen shall by ordinance order the

or repaired and the necessary grading, filling or parking done, as
the case may be, which notice shall be served on the parties by the
City Marshal by delivering a copy thereof to the said owner or owners
or his/her or their representatives. If such owner or owners and his/her
or their representatives are not residents of the City, or the City
Marshal shall make return that he/she is unable to find such owner
or owners or his/her or their representatives within the City, the
Street Commissioner or other person designated by the Board to perform
such work shall cause the notice to be published in some newspaper,
published in the City, for at least one (1) week. If such owner or
owners or his/her or their representatives fail or refuse to begin
the work specified in such notice, within fifteen (15) days after
being served as aforesaid, or after the last publication of such notice,
the Street Commissioner or other person designated by the Board shall
notify the contractor having the annual contract for the building
of sidewalks, or other persons to be designated by the Board, to construct
or reconstruct such sidewalk or the approaches, together with the
necessary grading, filling and parking, and in those cases where the
Board has ordered the repair of any sidewalk or approaches, the Street
Commissioner or other person designated by the Board shall repair
such sidewalk or approaches. The cost of such work shall be levied
as a special assessment and special tax bills issued therefor in the
manner provided by law and ordinance.
[CC 1976 §530.040; Ord. No. 629 §3, 2-9-1954]

of the cost of said work per cubic yard or per square yard, as the
case may be, and an estimate of the cost of the removal of any obstruction,
and no contract shall be let for a price in excess of said estimate
of the cost. After the bids are opened by the Board, the said Board

the other work as herein contemplated according to the specifications
adopted therefor.
